So we have a Simphonio and a Dragon and its even number 2+.
Don't encourage this, the 5$ Monk + are good earbuds.
Probably the production cost is the same.
michabarlevthe monks are good for $5 but they are eclipsed quickly by even the $20 Datura-x, $10yincrows, and basically any of the more popular aliexpress $20+ earbuds. These dragons are likely quite a bit better regardless of a tertiary parts estimate.
